My point is simply that as any competent mechanic knows, it is a bad
practice to put shear loads in the threaded area of a bolt. Were these
all-thread bolts and what type of loads were they designed for? It's
still difficult to believe that a pilot could put enough G on the
airplane to cause the ECM pod to depart the airframe.

Marron, for Christ's sake, what are you talking about??...'shear'
loads are "ACROSS THE BOLT". These bolts are installed so that
they will fail (when they do) by stripping the threads or
breaking the bolt "by STRETCHING it till the shank or the threads
fail".

A 'shear failure' will happen when a bolt is SHEARED off at ~90
degrees to the shank.

Why do you suppose it's called shear strength? and why do you
suppose shear strength is so much higher than tensile
strength?...god...

It is difficult to understand how FAA could continue to allow Marron to hold
and A&P certificate, in light of his obvious incompetence; in his delegated
area of expertise.
